Description

Detailed Description of the Invention [Field of Application of the Invention] The present invention relates to a drainage condenser and an evaporation plate installed on the drainage condenser to store defrosting water, and particularly to an evaporation plate suitable for increasing heat conduction. It concerns fixed structures.

[Background of the invention]

The conventional structure will be described below with reference to FIG. 5. Reference numeral 11 indicates a refrigerator body, and 12 indicates an observation chamber formed at the bottom of the main body 11. 13 is a drainage condenser that forms the lower surface of this machine room 12, and the raised part 13.13 has a hole in the rear part. have. 14 is a fixture for fixing the drain condenser 13 to the refrigerator main body 11. Reference numeral 15 is a defrost water evaporation tray installed on the top surface of the drain condenser. Although not shown in the figure, inside this evaporation tray 15, there is a defrost water evaporation tray installed on the top surface of the drain condenser. This is where the defrosting water is directed.

Therefore, it is necessary for the evaporating dish 15 to completely evaporate the flowing defrosting water using the heat of the drain condenser 13 before the next defrosting. For this purpose, it was necessary to improve heat exchange between the evaporating dish 15 and the drain condenser 13.As a means of achieving this, conventional refrigerators have a flat panel at the front end of the evaporating dish 15, as shown in the figure. The height should be slightly larger than the dimension between the refrigerator main body 11 and the drain condenser 13, and the height of the rear end of the evaporating dish 15 should be the same as the rear upright portion 13a of the drain condenser 13.
Slightly thicker than the height of the hole (and as a result, the refrigerator body 1
1 and the rear end rising portion 13a of the drain condenser 13, the evaporating dish 15 is pressed against the drain condenser 13. However, in this method, a gap is created near the center of the evaporating dish 15 due to variations in the pressing force due to variations in tolerances and warping of the bottom surface of the evaporating dish 15, and heat exchange between the evaporating dish 15 and the drain condenser 13 is not performed well ( If there is a gap or a gap occurs, the vibrations of the compressor are transmitted to the drain condenser 13, resulting in abnormal noise.

[Purpose of the invention]

In order to solve the above-mentioned conventional problems, the present invention provides locking parts for the drain condenser at approximately the center of the easily deformable bottom surface of the evaporating dish and at the left and right ends of the evaporating dish, thereby ensuring that both are in close contact with each other and providing a stable structure. The purpose is to achieve evaporation of defrosting water and also to prevent abnormal noise from occurring.

[Summary of the invention]

In other words, a cut-and-raised portion is provided at approximately the center of the drainage condenser, and a bent portion is provided by bending both ends of the drainage condenser into approximately 45 mm, and the position corresponds to the cut-and-raised portion and the bent portion. By providing the evaporating dish with claw-like protrusions and locking parts, the entire bottom of the evaporating dish is brought into close contact with the drain condenser.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. Reference numeral 1 denotes a refrigerator body, and the refrigerator body 1 is composed of an inner box 3 and an outer box 4 forming an interior 2, a foam heat insulating material 5, and the like. Reference numeral 6 indicates a front plate, and 7 indicates a base, each of which is fixed to the outer box 4. The front plate 6 has a hole for installing an evaporating dish 1o, which will be described later, on the drain condenser 9. 9 is a drainage condenser (drainage plate) 9a condensing pipe 9b
It is fixed to a front plate 6 at the front and a base 7 at the rear. Reference numeral 9C denotes a cut-out portion, which is provided integrally with the drainage plate 9a above the drainage plate 98 surface at approximately the center of the drainage condenser 9 and at a position corresponding to approximately the center of the evaporation plate 10, which will be described later. . Reference numeral 9d denotes a bent portion, which is formed by bending both side surfaces of the drainage plate 9a at approximately 45 degrees. The front end of the bent portion 9d is formed by an insertion portion 9C bent at 90 degrees and a guide portion 9f changing from 90 degrees to approximately 45 degrees. Reference numeral 10 denotes an evaporation dish, which is set on the drainage condenser 9, collects defrosting water from a cooler (not shown), and evaporates the defrosting water using the heat of the drainage condenser 9. 10. is a claw-like protrusion, which engages with the cut-out portion 9C at a position corresponding to the cut-out portion 9C at approximately the center of the bottom surface of the evaporation dish 10, and drains the bottom surface of the evaporation dish 10. It is molded integrally with the evaporating dish 10 in order to bring it into close contact with the evaporating dish 9a.

11 is a spring a, and a claw-like protrusion 10. The bottom surface of the evaporating dish is always pressed against the drain condenser plate 9a by its spring force.

Reference numeral 10b denotes a locking part, which is provided in plural pieces at both ends of the evaporating dish 10, and the lcn slope of the upper surface is approximately 45 degrees, so that the evaporating dish 10
It is integrally molded with. Reference numeral 12 denotes a spring b, which is attached to the approximately 45-degree inclined surface of the locking portion 10b described in nII, and whose upper surface abuts the bending cap 9b, and its spring force presses both ends of the evaporation plate 10 to the drain condenser plate 9a. It is designed to let you do so.

〔Effect of the invention〕

Since the present invention is constructed as shown below, the center of the bottom surface of the evaporating dish 1o, which was difficult to bring into close contact with the evaporating dish 1o, can be
By locking the cut-out portion 9c and the claw-like protrusion portion 10a, it is possible to achieve complete adhesion, complete evaporation of the defrosting water, and the spring installed between the two. Due to the function of a11, it is possible to absorb dimensional errors and to make the adhesion between the two more perfect. In addition, the cut-out portion 9c is molded integrally with the RJ water condenser plate 9a, and the claw-like protrusion portion 10° is molded integrally with the evaporating dish 10, so no special parts are required, which is very cost-effective. It's advantageous. Further, the locking portions 10b provided at both ends of the evaporating dish 10 are locked with the bent portions 9d provided at both ends of the drain condenser plate 9a, so that the entire bottom surface of the evaporating plate 10 comes into close contact with the drain condenser plate 9a. It is something that can be done.

Furthermore, a spring b1 is provided between the locking portion 10b and the bent portion 9a.
2 is attached, it is possible to absorb dimensional errors and further improve adhesion.

Furthermore, since the bent portion 9d and the locking portion 10b are each formed at approximately 45 degrees, when the two are locked, the force that stretches the evaporation plate 10 to the drain condenser plate 9a and the evaporation A force for positioning the dish 10 and the drain condenser plate 9a in the left-right direction is obtained at four o'clock, and the evaporation plate 10 is shifted in the left-right direction with respect to the drain condenser plate L/- plate 9a, causing the cut-out portion 90 and It is also possible to prevent the problem of being misaligned with the claw-like protrusion 10a and not being able to engage with each other.

In addition, the front end (this insertion = qs 9 e
Since the guide portion 9f is formed, when inserting the steam-free plate 10 from the front, the force of the locking portion 10b is smoothly applied to the bending portion 9d, which further improves maneuverability. be.

In addition, the bottom center of the evaporating dish 10 and both sides (till mi
Since it is securely fixed to the drain condenser plate when the force is ≤1, it is possible to prevent abnormal noise from occurring.
